If the total amount of all fees received by the office of the chancery clerk or by the office of the circuit clerk in any year are insufficient to pay the expenses of the office for that year, the clerk shall notify the board of supervisors, and if the board of supervisors makes a finding and enters on its minutes the finding that the fees received by the office of the clerk are insufficient to pay the expenses of the office for that year, then the board of supervisors, in its discretion, may appropriate funds from the general fund of the county to the office of the clerk as necessary to supplement the payment of the expenses of the office of the clerk.
